Int. Cl. Cb 33/00 US. Cl. 202-263 6 Claims ABSTRACT OF THE DISCLOSURE A gastight hood is mounted to a coke guide car. The hood is provided with a collar that cooperates with a fixed gas collecting main and with curtains that prevent gases, smoke and dirt from escaping from the quenching car while coke is being pushed.

BRIEF SUMMARY OF THE INVENTION The invention is related to coke ovens and more particularly to apparatus for collecting and removing effluent emitted while coke is being pushed from a coke oven chamber.

The apparatus includes a hood that is mounted to a coke guide car that carries a coke guide. The coke guide is adapted to coact with the face of a coke oven and with the hood. An efiluent collecting main is fixed in position alongside of the coke oven battery and has a plurality of doors that are disposed opposite the coke oven chambers.

An adjustable collar cooperates with the hood and efliuent collecting main to form a seal and to open the door when coke is pushed from a coke oven chamber, and an adjustable pair of curtains are mounted to the hood which are movable to form a seal with the hood and a coke quenching car that moves relative to the hood. For a further understanding of the invention and for features and advantages thereof reference may be made to the following description and thedrawings which illustrate a preferred embodiment of the invention.

BRIEF DESCRIPTION OF. THE DRAWINGS In the drawings:

FIG. 1 is a side elevational view of apparatus in accordance with the invention; FIG. 2 is a view along line Ila-11 of FIG. 1; and

FIG. 3 is a view of a portion of the apparatus of FIG. 1 in another operative position.

DETAILED DESCRIPTION FIG. 1 illustrates a portion of a coke guide fume collecting system 11 in accordance with the invention that includes: a coke guide car 13 that is carried on rails 15; a frame 17 mounted to the coke guide car 13; a fume hood 19 supported by the structural frame 17; and a fume collecting main 21.

The coke guide car 13 is provided with conventional trucks having wheels 23 that engage rails 15. At a convenient location on the coke guide car 13, such as at 25, a vertical support member 27 is pin connected to the coke guide car 13. The member 27, forming part of the frame 17, is also supported by a carriage 29 having wheels 31 that coact with a rail 33 supported on suitable adjacent fixed structure 35.

In FIG. 1 there is indicated in phantom outline a coke quenching car 37 which is conventional. FIG. 1 also shows a conventional coke guide 39 in the racked-out, operative position. That is to say, the coke guide 39' is in abutting relation to the fume hood 11 and a coke oven chamber (not shown). The coke guide 39 is, of course, mounted in a usual manner to the coke guide car 13.

The fume hood 19 is provided with a telescopable collar 41 at the end adjacent the fume collecting hood 21. The collar 41 is fixed to a carriage 43 that is movable on wheels 45 supported by the frame structure 17. The carriage 43 carries a dog 47 that is connected by clevis 49 to a piston rod 51 of the cylinder-piston assembly 53. One preferred type of cylinder-piston assembly 53 is the Electric Cylinder manufactured and marketed by RACO Machine Company, Pittsburgh, Pa., but other types of cylinder-piston assemblies may be used if they are preferred. The cylinder-piston assembly 53 is pivotally mounted to the frame structure 17 for movement about an axis in the trunnions 55.

The carriage 43 also carries a dependent other dog 57 which is provided with a roller 59 journaled thereto. The roller 59 is engageable with an arm 61 mounted to and extending outwardly from a pivotally mounted door 63 journaled to the collecting main 21.

The collecting main 21 is fixed to suitable supporting structure and extends the full length of the coke oven battery. It may be connected to an exhaust and gas scrubhing system that exerts a slight negative pressure within the collecting main in order to more effectively remove the gases, smoke and dirt from the fume hood 19 when coke is pushed.

The collecting main 21 is provided with a plurality of the pivotally mounted doors '63 which are disposed opposite respective coke oven chambers.

The frame structure 17 also supports a pair of curtains 65, 67 that are arranged in spaced apart relation in a vertical plane that is parallel to the rails 15. Each curtain 65, 67 is associated also with a flat, horizontal covers 69, 71 that are disposed above and over the quenching car 37, as suggested in FIGS. 1 and 2.

Each curtain 65, 67 and its associated cover 69, 71 is supported by framework 73 that is connected to pairs of chains 75. The chains 75 are secured to the main frame structure 17 as suggested in FIGS. 1 and 2. The main frame structure 17 carries, Where indicated in FIGS. 1 and 2, another cylinder-piston assembly 77 that is or can be similar to the cylinder-piston assembly 53.

The piston rod portion 79 of the cylinder-piston assembly 77 is connected to a bell-crank 81 that is journaled to the frame 17. The depending ends of the bell-cranks 81 are each provided with an outwardly extending rod or finger 83 which engages an upstanding dog 85 mounted to the framework 73 about Where shown in FIG. 1.

In operation, the coke guide car 13 is moved in the usual manner along the rails 15 to a coke oven chamber that is to be pushed, the door of which has previously been removed. When the coke guide moves along the track, the collar 41 is retracted, as shown in FIG. 3, and the curtains 65, 67 are in the raised position, which is effected when the cylinder-piston 77 is retracted.

After the coke guide is aligned with the oven chamber, the coke guide itself 39 is brought into abutting relation with the face of the coke oven battery andis extended into an opening 87 (FIG. 2) of the frame structure 19. Thereupon, the cylinder-piston assembly 53 is activated to move the carriage 43 toward the collecting main 21. The roller 59 first contacts the upstanding arm 61 and the door 63 commences to pivot clockwise. At the same time the collar 41 moves into position abutting the collecting main 21 thereby forming a sealing relation.

The coke quenching car 37 is then placed in position, as is customary, to receive coke. The cylinder-piston 77 is now extended to lower the vertical curtains 65, 67 which form a shield to prevent the escape of gases, smoke and dirt from the fume hood 19 when coke is pushed.

The coke passes through the coke guide and falls in the direction of arrow A into the coke quenching car, and the gases, smoke and dirt flow upward in the direction of arrow B into the collecting main 21. Of course, as the coke is being pushed, the coke quenching car moves along the rails and the coke is distributed uniformly in the car in the customary manner.

After pushing is completed, the cylinder-piston 53 is actuated to retract the collar and to close the door on the collecting main. Simultaneously, or nearly so, the cylinder-piston 77 is actuated to raise the curtains again; the fingers 83 contacting the dogs 85 and rotating the curtains clockwise.

Thereafter the coke guide car is ready to be moved to the next oven for pushing; the coke quenching car meanwhile being moved to the quenching station as is customary.

From the foregoing description of one embodiment of the invention, those skilled in the art should recognize many important features and advantages of it, among which the following are particularly significant:

That the apparatus of the invention is most effective in preventing gases, smoke, dirt and the like from escaping when coke is pushed because even the coke quenching car is shielded by a pair of curtains; and

That the structure is adaptable for installation on existing as well as new coke oven batteries.
